However, Monchi is adamant that no more first-team players will be moved on and is confident that Roma will have a strong side by the time the transfer window closes at the end of August.

"Nainggolan will definitely stay at Roma," he told a news conference. "The time of selling important players is over. Now we build a team with the options that the market provides.

"One of the objectives we are working on is a winger and we'll try to get that done as quickly as possible. I prefer to wait and bring in the player I really want, rather than to act hastily."

Kostas Manolas continues to be linked with a move to Zenit but Monchi does not want the club's defensive options to become any weaker.

"We want one more centre-back, without anyone else leaving," he said. "A team is built not on July 1, but at the end of August. Once the transfer window closes, we'll have a very good squad. We are building a team capable of fighting and being competitive."

However, the former Sevilla director confessed that Roma's pursuit of forward Gregoire Defrel has been complicated by Sassuolo's asking price.
